Effectiveness of Automatic and Manual Calibration of an Office Building Energy Model

open access: yesApplied Sciences, 2019
Energy reduction can benefit from the improvement of energy efficiency in buildings. For this purpose, simulation models can be used both as diagnostic and prognostic tools, reproducing the behaviour of the real building as accurately as possible.

On the Calibration of Full-polarization 86GHz Global VLBI Observations [PDF]

open access: yes, 2012
We report the development of a semi-automatic pipeline for the calibration of 86 GHz full-polarization observations performed with the Global Millimeter-VLBI array (GMVA) and describe the calibration strategy followed in the data reduction.
